WATER-BACK FOR RANGES OR STOVES.

SPECIFICATION forming part of Letters Patent No. 653,949, dated July 1'7, 1900.

Application filed February 5, 1900. Serial No. 4,098. (No model.)

T all whom, it 77m3/ concern:

Be it known that I, TALTER L. CULVER, of the city of St. Louis, State of Missouri, have invented certain new and useful Improvements in lVater-Backs for Ranges or Stoves, of which the following is a full, clear, and eX- act description, reference being had to the accompanying drawings, forming a part hereof.

This invention relates to water-backs for ranges and stoves; and it consists of the novel construction, combination, and arrangement of parts hereinafter shown, described, and claimed.

The object of this invention is to provide an improved water-back for ranges by means of which the noise which is nsually incident to heating water by water-backs of the usual construction is obviated, while at the same time the water to be heated is circulated more freely and rapidly over the heating-surface.

In the drawings, Figure 1 is a view showing my improved water-back in use, the range and the water-reservoirbeing in section. Fig. 2 is a Vertical sectional view taken through the center. Fig. 3 is a view in perspective showing the device in detail.

Referring by numerals to the accompanying drawings, l indicates the end or base of the water-back, integral with which are the sides, top, and bottom. The top 2 occupies a horizontal plane when in use and is provided with an integral fiange or seat 3 near its rear end and at a suitable distance from the end or base 1 and with a rounded fiange or nutseat 4: near its forward end. The sides 5 are also integral with the end or base 1 and with the top 2, and each is provided with a suitable projection 6, the same in continuation of the flange 3. The inclined bottom 7, like the top and sides, is cast integral with the back and with the sides and is provided with an integral fiange or seat 8 in alinementwith the fiange 3 and projection 6. The said sides, top, and bottom converge at their forward end and form an integral threaded projection 8a. The base or end 1 is provided With ,an integral apertured ear 9, the same being in alinement with the fianges' and 8 and With the projection 6, all of which are adapted to rest against the interior of the stove 10 when the device is in use.

Then the device is applied, it is placed within the fireplace in the range and projected laterally through an aperture until the flanges 8, 6, and, 8 rest against the interior of the range. When so applied the base or end 1 is held in alinement with the lining of the range,and the receptacle formed by the sides, top, and bottom projects laterally and is connected to the reservoir or water-receptacle 10a by projecting the threaded projection 8 through an aperture in the said receptacle and applying a nut 11 to the said projection. Before so adj Listing the parts the gum washer 12 is placed over the threaded projection and forms a very close connection with the waterreceptacle, so that none of the water may escape around the projection,and thereby cause inconvenience.

It will be noticed from thedrawings and 7o v description that one of the main and essential features of my invention is in constructing a water-back provided'on its top interior surface with a smooth and unobstructed surface, so that the rise and expansion of the water and steam when heated may pass unobstructed over' a smooth surface, and the same not being resisted in any manner absolutely prevents any gurgling or bubbling of the water in the Water-tank.

A water-back constructed in accordance with the above principles possesses Superior advantages over all others and effectually overcomes all objections which have heretofore been urged against devices of this class. By this improved construction, wherein a horizontal unobstructed top wall is presented for the passage of the heated particles and the lower wall is inclined downwardly in the direction of the heat-absorbing surface the water is allowed to circulate freely into and out of the device and no unpleasant noise is created thereby. By this form of the device a greater heat-absorbing surface is presented to the action of the fire 5 also; the cooler water is permitted to gravitate to the lowestl point of the said heat-absorbing surface and rises along with the same While being heated and to escape into the tank Without materially interfering With the infiowing current. No steam is allowed to congregate in the top and the noise incident to its escape is obviated. In all these and in other respects the device presents improvements over the ordinary construction and the cost involved in its construction or manufacture is not great.

I claim- 1. The herein-described water-back, comprising a casting having a base or end, a horizontal unobstructed top, Vertical sides, a bottom inclined downwardly in the direction of the heat-absorbing surface, and a tubular projection integral With the said sides, top and bottom, the said tubular projection being in horizontal alinement With the said top, substantially as specified.

2. The herein-described water-back, comprising a casting having a baseor end, a horizontal unobstructed top, Vertical sides, a bottom inclined downwardly in the direction of the heat-absorbing surface, fianges integral With the said sides, top and bottom for holding the said base a suitable distance from the side of the range, a tubular projection integral with the said sides, top and bottom in horizontal alinement With the top and devoid of internal projections, and a means for connecting the said tubular projection With the Water-receptacle, substantially as specified.

3. As an article of manufacture, a Waterback for ran ges provided With suitable flanges for attachin g it to the range, a screw-threaded nipple for attaching the Water-tank to the Water-back, said Water-back havinga bottom wall inclined downwardly in the direction of the heat-absorbing surface, a smooth and unobstrncted interior surface at its top, substantially as specified.

4:. As an article of manufacture, a Waterback for ranges provided with a base or end having integrally formed therewith suitable fianges for attachment to the range, a top wall proj ectin g horizontally and at right angles toA said fire-surface wall and having its interior surface smooth and unobstructed, the lower Wall proj ectin g upward at an acute angle from said base or end, and a screW-threaded nipple formed integral with said walls, substantially as specified.

In testimony Whereof I affix 'my signature in presence of two Witnesses.
